THE BEST MODES FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will bedescribed in more detail with reference to the accompanying drawings.

FIG. 2 illustrates a schematic block diagram of the wireless internetconnection system using number-based domain according to a preferredembodiment of the present invention.

As shown in FIG. 2, the wireless internet connection system usingnumber-based domain may comprise mobile terminals 200 a, . . . , 200n(hereinafter will be named a mobile terminal 200), a based station 210,an IWF (interworking function device) 220, a converter 230, a router240, a contents provision server 250, and a persnet server 260.

The mobile terminal 200 transmits a number domain connection requestsignal including number domain information which a user inputted to thebase station 210 and receives contents of a site corresponding to thenumber domain information included in the number domain connectionrequest signal.

On connecting the internet using the mobile terminal 200, the domaininformation may be inputted by inputting number domain corresponding toa site or inputting letter domain.

The number domain connection request signal may comprise an identifier,a number domain code which user inputted and a user index foridentifying user. According to an embodiment of the present invention, auser phone number may used as a user index and other user identificationmeans may be used as the user index.

The base station 210 receives the number domain connection requestsignal from the mobile terminal 200, transmits it to the IWF 200 andreceives contents of the site from the IWF, transmits it to the mobileterminal 200.

Although it is not illustrated in FIG. 2, a mobile switching center maybe included in the wireless internet connection system between the basestation 210 and the IWF 220. The number domain connection request signalis transmitted to the mobile switching center through a base stationcontroller. If the mobile switching center receives the number domainconnection system, the mobile switching center recognizes that it shouldbe transmitted to the IWF 220 through the identifier and transmits it tothe IWF 200.

The IWF has function of modem and PPP server, which enables users totransmit data only with the mobile terminal without wireless modem andkeeps the connection between the mobile terminal and internet orcomputer network.

In other words, the IWF 220 transforms a mobile communication protocolinto an internet protocol when signal is transmitted from mobilecommunication network to internet and transforms an internet protocolinto a mobile communication protocol when signal is transmitted frominternet to mobile communication network.

The converter 230 receives the number domain connection request signalfrom the mobile terminal 200 and determines if the signal is a numberdomain connection request signal or a letter domain connection requestsignal through the identifier of the signal. If the received signal isthe number domain connection request signal, the converter 230 analyzesthe number structure of the number domain information and determines ifthe analyzed number structure exists.

If the number structure corresponding to the transmitted number domainexists, the converter 320 converts the number domain into a real domain(for example, English or Korean letter domain) and transmits theconverted domain to the router 240.

The number domain may comprise plurality of numbers, according to apreferred embodiment of the present invention, the number domain maycomprise contents classification number, the first domain number and thesecond domain number.

The first domain number means a number corresponding to the highestdomain number which includes co.kr, net, org, com, ac.kr.

The second domain number means a number corresponding to a name of asite which includes game, chosun, etc.

The contents classification number is a number for classifying the kindof the site to be connected. For example, the contents classificationnumber is 111 for game, 114 for traffic information, 1472 for newsinformation and the contents classification number is predetermined. Theconverter 230 searches a database in order to output the letter domaincorresponding to the number domain. At this case, it is preferable forthe database to store the number domain and the letter domaincorresponding to the number domain based on the kind of the contents,which reduces database search time.

For example, if the number domain is 11142631, the converter classifiesthe 11142631 to 111,4263,1.

111 is contents classification number corresponding to game relatedcontents, 4263 is the second domain number corresponding to ‘game’. Thesecond domain number is the number corresponding to the name of the sitewhich user requests to connect using mobile terminal.

Referencing FIG. 1, in case of ‘game’, 4 is pressed once for g, 2 ispressed once for a, 6 is pressed once for m, and 3 is pressed two timesfor e, which means that the second domain number is a numbercorresponding to letter in mobile terminal. However according to anotherembodiment of the present invention, the second domain number may bearbitrarily designated number by a service provider.

1 which is the first domain number may be predetermined as ‘co.kr’. Inthe same way, 2 may be predetermined as ‘com’ and 3 may be predeterminedas ‘net’. Otherwise, the first domain number may be number correspondingto English letter in mobile terminal.

In number domain, the number of bytes allocated to the eachclassification number is predetermined.

In above mentioned number domain 11142631, 111 represents game relatedcontents, 4263 represents ‘game’, 1 represents ‘co.kr’. The convertersearches game related field of the database through 111 and recognizesthat 4263 and 1 represent ‘game’ and ‘co.kr’ respectively and converts11142631 to ‘game.co.kr’. The converter transmits the transformed domainto the router 240.

If the received domain from the mobile terminal 200 is a letter domainsuch as game.co.kr, the converter 230 transmits the received domaininformation directly to the router 240. As mentioned above, the kind ofdomain is determined through the identifier included in the signal.

The router 240 sets up the path so that the mobile terminal 200 isconnected to the converted domain by converter 230.

The contents provision server 250 provides various inter services. Thecontents provision server 250 provides various information to the mobileterminal 200.

The persnet server 260 is managed by mobile communication entrepreneur.The mobile communication user can receive various kind of servicesselectively through persnet server 260. More particularly, the persnetserver 260 provides services such as internet surfing, chatting, email,mobile banking, electronic commerce, geographic service, news, stocks,weather, traffic information, job, record information, game, etc.

According to another preferred embodiment of the present invention, thecontents provision server 250 and the persnet server 260 may beimplemented as one server and provide various kind of services to themobile terminal 200.

According to another preferred embodiment of the present invention, theconverter 230 and the router 240 may be implemented as one device. Forexample, a router which functions as router and converter together maybe used.

At this case, the router 240 receives the connection request signal fromthe mobile terminal 200 and determines if the received signal is thenumber domain connection request signal or the letter domain connectionrequest signal.

If the received signal from the mobile terminal 200 is the number domainconnection request signal, router 240 analyzes the number structure ofthe number domain information, converts the number domain into theletter domain corresponding to the analyzed number structure, and thenconnects the mobile terminal 200 to the converted domain.

In case the received domain is letter domain such as ‘game.co.kr’, therouter connects the mobile terminal 200 to the received domain.

FIG. 3 illustrates a flow chart showing process of connecting wirelessinternet using number domain according to a preferred embodiment of thepresent invention,

Referencing FIG. 3, the converter receives an internet connectionrequest signal from the mobile terminal S300.

The converter which received the internet connection request signaldetermines if the received signal is number domain connection requestsignal or the letter domain connection request signal through theidentifier of the signal S302.

If the received signal is the number domain connection request signal,the converter analyzes the number structure of the number domain andsearches if a number structure corresponding to the analyzed numberstructure exists S304.

If a number structure corresponding to the analyzed number structureexists, the converter converts the received number domain into a letterdomain S308.

For example, if a user of the mobile terminal inputs domain informationas ‘11142631’, the inputted domain information is transmitted to theconverter through the base station and the IWF. The converter classifiesreceived ‘11142631’ into 111, 4263, 1. Then, the converter searches if anumber structure corresponding to the analyzed 111, 4263, 1 exists inpre-stored domain information number structure.

If the analyzed number structure exists, the converter searches if theletter domain matching the analyzed number structure exists. If thematching letter domain is ‘game.co.kr’, the converter converts thenumber domain into ‘game.co.kr’ and transmits it to the router.

As mentioned in above example, the converter transmits the converteddomain to the router S310.

When the number domain is converted to the letter domain, the numberdomain classification structure is pre-stored in converter.

According to another embodiment of the present invention, the numberdomain may be an arbitrarily designated number (For example, ‘1111’).

The converted letter domain matching the number domain is transmitted tothe router by the converter. The router searches converted letter domainand sets up the path in order to connect the mobile terminal to thedomain.

By connecting the domain, the site information corresponding to theletter domain is transmitted and displayed in the mobile terminal.

If the inputted domain information by the mobile terminal user is theletter domain such as ‘game.co.kr’ S312, the domain information istransmitted to the router through the base station, the IWF and theconverter. The router searches if the received letter domain informationexists S314.

If the site corresponding to the received letter domain exists, the siteinformation is transmitted and displayed in the mobile terminal.

FIG. 4 illustrates a flow chart showing the process of connecting theinternet and receiving contents after connecting the internet accordingto another embodiment of the present invention.

Referencing FIG. 4, the mobile terminal receives the internet connectionrequest information from the user S400. If the internet connectionrequest is inputted from the user, domain input screen is displayed inthe mobile terminal S402. A menu is provided in the displayed screen sothat the user can select number domain connection or the letter domainconnection.

The user selects at least one domain connection from the menu (S404). Ifthe user selects number domain connection, the user inputs the numberdomain information of the site which the user wants to connect (Forexample, if the user wants to connect chosun.com, the user inputs ‘1472’which represents news related contents, ‘246786’ which represents thename of the site and ‘2’ which represents corn, therefore combinednumber domain is ‘14722467862’) and the mobile terminal generates thenumber domain connection request signal and generated number domainconnection request signal is transmitted to the converter through theIWF.

The converter analyzes the number structure of the received numberdomain and searches if the analyzed number structure exists inpre-stored number structure. If the analyzed number structure exists inpre-stored number structure, the router searches if the letter domainmatching the number domain exists. If the letter domain matching thenumber domain exists, the converter converts the number domain into theletter domain matching the number domain and transmits it to the routerS410.

The router sets up the path in order for the mobile terminal to connectto the letter domain and by the path connects the mobile terminal to thereceived domain S412.

If the user of the mobile terminal selects letter domain, letter domaininformation (For example, ‘chosun.com’) is transmitted to the routerS414.

The router searches transmitted domain and connects the mobile terminalto the domain S416.

As mentioned above, the mobile terminal is connected to the domain whichthe user wants to connect, the homepage information corresponding to thedomain is transmitted to the mobile terminal S418, and main screen ofthe site is displayed in the mobile terminal S420.

The user selects necessary item in the displayed main screen S422. Ifthe user selects an item, information corresponding to the item isdisplayed in the mobile terminal S424. The displayed information istransmitted in divided size corresponding to the size of the LCD displayof the mobile terminal.

For example, the case that user of the mobile terminal connects theportal site ‘naver.com’ and selects computer item is explained. If theuser selects the number domain, the user may input ‘1343628372’ (‘1343’represents portal site classification, ‘62837’ represents naver which isnumber button corresponding to letter naver in mobile terminal, ‘2’represents com). If the user selects the letter domain, the user inputsn, a, v, e, r, ., c, o, m. If the mobile terminal is connected to thesite, main screen including various items such as news, game, computer,health, etc is displayed.

In the displayed main screen, the user selects computer item. Afterselecting the computer item, if the user selects necessary item indisplayed screen sequentially, selected information is transmitted tothe mobile terminal.

The information is transmitted in divided size corresponding to the sizeof LCD, because the LCD of the mobile terminal is small.

The method of dividing information to the size corresponding to the sizeof the mobile terminal LCD is explained below.

The line of the information which the mobile terminal user selected isanalyzed and each line is converted to the size that matches the size ofthe LCD screen and converted line is transmitted. The user may selectnecessary information using scroll key of the mobile terminal among thetransmitted information.

According to another embodiment of the present invention, number domainmay be series of numbers corresponding to letters of letter domain.

For example, ‘ez-patent.co.kr’ is converted to 210.107.46.101 in theinternet, and the user may connect to the site ‘ez-patent.co.kr’ byinputting 210.107.46.101 or the user may connect to the site‘ez-patent.co.kr’ by inputting 3 corresponding to e, 1 corresponding toz, 7 corresponding to p, 2 corresponding to a, 8 corresponding to t, 3corresponding to e, 6 corresponding to n, 8 corresponding to t, 1corresponding to co.kr.

FIG. 5 illustrates a flow chart showing process of registeringnumber-base domain homepage according to a preferred embodiment of thepresent invention.

Referencing FIG. 5, an operator of homepage selects number registrationmode of the homepage using mobile terminal or telephone in order toregister number-domain homepage S500.

If the operator selects the registration mode, homepage registrationnumber input window is displayed and the operator inputs arbitrarynumber in displayed homepage registration number input window (S502).

For example, if the operator of the daum.net site would like to registerthe site as number domain, the operator selects the homepage numberregistration mode and inputs arbitrary number domain in homepageregistration number input window.

The number domain of daum.net, for example, may be 134332863. In134332863, 1343 represents portal site, 3286 is number corresponding todaum, 3 represents net by the above mentioned number structure, or thenumber domain of daum.net may be 1234 which is arbitrarily determinednumber by the homepage operator.

The converter which received the number domain searches if the samenumber domain exists in server S504. If the same number does not exist,the number domain inputted by the operator is registered as the numberdomain of the corresponding homepage.

For example, in case that daum.net is registered as 1234, a mobileterminal user selects domain input menu, and then press 1234 usingnumber button and corresponding homepage is displayed.

If the same number as the number which the site operator inputtedexists, step 502 proceeds again.

According to another embodiment of the present invention, the mobileterminal user can store the domain by designating a particular numberfor preferred site. The user can connect the site using the designatednumber.

For example, a mobile terminal user preferring chosun.com site designatedesignates 1 for chosun.com and if the user would like to connect tochosun.com, the user can connect to the site by selecting 1 in internetconnection mode.

FIG. 6 illustrates an example of initial connection screen according toa preferred embodiment of the present invention, and FIG. 7 illustratesan example of screen display of selecting internet connection accordingto a preferred embodiment of the present invention.

If a mobile terminal user selects menu for connecting internet, screenas FIG. 6 is displayed. If the user selects domain input menu shown inFIG. 6, a message that select a letter domain or a number domain isdisplayed in screen as shown in FIG. 7. The mobile terminal user selectsat least one of a letter domain and a number domain.

If the mobile terminal user selects the letter domain, the user inputsletter domain of the site and selects execution button.

For example, in case the mobile terminal user would like to connecthomepage of chuosunilbo, the user inputs chosun.com and selectsexecution button.

If the mobile terminal user selects the number domain, the input windowfor inputting number domain is displayed in the mobile terminal. Theuser inputs the number domain and selects execution button.

If the execution button is selected, the inputted number domain istransmitted to the converter through the IWF and the number structure isanalyzed by the converter. The converter converts the number domain intothe letter domain corresponding to the analyzed number structure. Theuser can connect to the homepage corresponding to the converted letterdomain.
